The Studio Stable Database Server is a database server for REAL Studio. It's written in REAL Studio itself and uses REALSQLDatabase on the server. So basically turning a server interface over SQLite and the same as REALserver was. But the backend as well as the interface is both written in REALbasic instead of C/C++.
Today I tested it. I can install my SQLite extension by simply copying the extension file into the extensions folder. Once that is done, I can use the SQL commands and enjoy my functions.
See this example code which connects to a local server and performs the UsernameMBS function:

// run a functiondim r as SSRecordSet = ssdb.SQLSelect("select UserNameMBS()")

if r<>nil then// show result of function MsgBox r.IdxField(1).StringValueelse MsgBox ssdb.errorMessageendifelse MsgBox ssdb.errorMessageendifEnd

PS: There is a special offer available this week (until 27th February) for the license with source code. Maybe a good chance? With source code you can modify the whole server to your needs.
